Labor is to outline an election pledge today where they will push to decriminalise abortions as well as offer the procedure for free.

The procedure is to be taxpayer-funded and offered in public hospitals with late-term abortions also potentially on offer.

Tanya Plibersek, Opposition spokeswoman for Women, said a federal Labor government would require public hospitals to offer termination services as part of their Commonwealth funding arrangement.

However, abortion is still illegal in New South Wales and South Australia unless the female or foetus is deemed to be at risk, so in order for Labor to follow through with their election pledge they must convince the state governments to decriminalise the procedure.
